I am always amazed at how some people can claim that a raw or cooked  palaeolithic diet is too expensive. This just isn't so.  For example, if one is near the coast, raw wildcaught seafood can be bought at very cheap prices(eg:- mackerel or sardines). If one finds grassfed muscle-meats too expensive, then one should instead buy the dirt-cheap  grassfed organ-meats which nobody wants in the West, but  which are, ironically, far more nutricious than any muscle-meats. Then there is the possibility of wild game, which I have been easily able to get hold of at much, much cheaper rates than grassfed meats, and  the former  are far higher in healthy nutrients  as well.
 
There are other savings.- if one is doing palaeo strictly, then cutting down on  alcohol and smoking  would help reduce daily costs, not to mention greatly reducing future expensive stays in hospital. Being strictly palaeo also means not eating sweets or chocolates or fizzy drinks/energy drinks or other processed/preprocessed "foods", which is another saving. Lastly, if one were to adopt the very palaeolithic dietary habit of Intermittent Fasting, then  one would cut down on the  overall amount of food bought while still staying healthy.
